In my home DAW, everything runs in Sonar. I have Kontakt 1.5x as my primary tool for loading patches, converting file extensions etc., but except for occasional minor soft-sound tweaks, I've barely scratched the surface of its potential.
My question is: Is there really any compelling reason to spend the $149 to upgrade to K2? The main reason I've found so far is that new samples for Kontakt (such as Prominy) don't seem to be backward compatible, but if that's all, then it's a back-burner priority for me. But NI has some interesting looking free downloads for K2 owners, and I've heard some good things about the included sound library.
What do people think? Are the new features, interface, or sonic enhancements such that it makes the upgrade a no-brainer?
Any thoughts would be appreciated.
